In a chained pipeline, the result of the each command is -passed as the last argument of the following command. The output of the final -command in the pipeline is the value of the pipeline. - -The output of a command will be either one value or two values, the second of -which has type error. If that second value is present and evaluates to -non-nil, execution terminates and the error is returned to the caller of -Execute. - -Variables - -A pipeline inside an action may initialize a variable to capture the result. -The initialization has syntax - - $variable := pipeline - -where $variable is the name of the variable. An action that declares a -variable produces no output. - -If a "range" action initializes a variable, the variable is set to the -successive elements of the iteration. Also, a "range" may declare two -variables, separated by a comma: - - range $index, $element := pipeline - -in which case $index and $element are set to the successive values of the -array/slice index or map key and element, respectively. Note that if there is -only one variable, it is assigned the element; this is opposite to the -convention in Go range clauses. - -A variable's scope extends to the "end" action of the control structure ("if", -"with", or "range") in which it is declared, or to the end of the template if -there is no such control structure. A template invocation does not inherit -variables from the point of its invocation. - -When execution begins, $ is set to the data argument passed to Execute, that is, -to the starting value of dot. - -Examples - -Here are some example one-line templates demonstrating pipelines and variables. -All produce the quoted word "output": - - {{"\"output\""}} - A string constant. - {{`"output"`}} - A raw string constant. - {{printf "%q" "output"}} - A function call. - {{"output" | printf "%q"}} - A function call whose final argument comes from the previous - command. - {{printf "%q" (print "out" "put")}} - A parenthesized argument. - {{"put" | printf "%s%s" "out" | printf "%q"}} - A more elaborate call. - {{"output" | printf "%s" | printf "%q"}} - A longer chain. - {{with "output"}}{{printf "%q" .}}{{end}} - A with action using dot. - {{with $x := "output" | printf "%q"}}{{$x}}{{end}} - A with action that creates and uses a variable. - {{with $x := "output"}}{{printf "%q" $x}}{{end}} - A with action that uses the variable in another action. - {{with $x := "output"}}{{$x | printf "%q"}}{{end}} - The same, but pipelined. - -Functions - -During execution functions are found in two function maps: first in the -template, then in the global function map. By default, no functions are defined -in the template but the Funcs method can be used to add them. - -Predefined global functions are named as follows. - - and - Returns the boolean AND of its arguments by returning the - first empty argument or the last argument, that is, - "and x y" behaves as "if x then y else x". All the - arguments are evaluated. - call - Returns the result of calling the first argument, which - must be a function, with the remaining arguments as parameters. - Thus "call .X.Y 1 2" is, in Go notation, dot.X.Y(1, 2) where - Y is a func-valued field, map entry, or the like. - The first argument must be the result of an evaluation - that yields a value of function type (as distinct from - a predefined function such as print). The function must - return either one or two result values, the second of which - is of type error. If the arguments don't match the function - or the returned error value is non-nil, execution stops. - html - Returns the escaped HTML equivalent of the textual - representation of its arguments. - index - Returns the result of indexing its first argument by the - following arguments. Thus "index x 1 2 3" is, in Go syntax, - x[1][2][3]. Each indexed item must be a map, slice, or array. - js - Returns the escaped JavaScript equivalent of the textual - representation of its arguments. - len - Returns the integer length of its argument. - not - Returns the boolean negation of its single argument. - or - Returns the boolean OR of its arguments by returning the - first non-empty argument or the last argument, that is, - "or x y" behaves as "if x then x else y". All the - arguments are evaluated. - print - An alias for fmt.Sprint - printf - An alias for fmt.Sprintf - println - An alias for fmt.Sprintln - urlquery - Returns the escaped value of the textual representation of - its arguments in a form suitable for embedding in a URL query. - -The boolean functions take any zero value to be false and a non-zero -value to be true. - -There is also a set of binary comparison operators defined as -functions: - - eq - Returns the boolean truth of arg1 == arg2 - ne - Returns the boolean truth of arg1 != arg2 - lt - Returns the boolean truth of arg1 < arg2 - le - Returns the boolean truth of arg1 <= arg2 - gt - Returns the boolean truth of arg1 > arg2 - ge - Returns the boolean truth of arg1 >= arg2 - -For simpler multi-way equality tests, eq (only) accepts two or more -arguments and compares the second and subsequent to the first, -returning in effect - - arg1==arg2 || arg1==arg3 || arg1==arg4 ... - -(Unlike with || in Go, however, eq is a function call and all the -arguments will be evaluated.) - -The comparison functions work on basic types only (or named basic -types, such as "type Celsius float32"). They implement the Go rules -for comparison of values, except that size and exact type are -ignored, so any integer value, signed or unsigned, may be compared -with any other integer value. (The arithmetic value is compared, -not the bit pattern, so all negative integers are less than all -unsigned integers.) However, as usual, one may not compare an int -with a float32 and so on. - -Associated templates - -Each template is named by a string specified when it is created. Also, each -template is associated with zero or more other templates that it may invoke by -name; such associations are transitive and form a name space of templates. - -A template may use a template invocation to instantiate another associated -template; see the explanation of the "template" action above. The name must be -that of a template associated with the template that contains the invocation. - -Nested template definitions - -When parsing a template, another template may be defined and associated with the -template being parsed. Template definitions must appear at the top level of the -template, much like global variables in a Go program. - -The syntax of such definitions is to surround each template declaration with a -"define" and "end" action. - -The define action names the template being created by providing a string -constant. Here is a simple example: - - `{{define "T1"}}ONE{{end}} - {{define "T2"}}TWO{{end}} - {{define "T3"}}{{template "T1"}} {{template "T2"}}{{end}} - {{template "T3"}}` - -This defines two templates, T1 and T2, and a third T3 that invokes the other two -when it is executed. Finally it invokes T3. If executed this template will -produce the text - - ONE TWO - -By construction, a template may reside in only one association. If it's -necessary to have a template addressable from multiple associations, the -template definition must be parsed multiple times to create distinct *Template -values, or must be copied with the Clone or AddParseTree method. - -Parse may be called multiple times to assemble the various associated templates; -see the ParseFiles and ParseGlob functions and methods for simple ways to parse -related templates stored in files. - -A template may be executed directly or through ExecuteTemplate, which executes -an associated template identified by name. To invoke our example above, we -might write, - - err := tmpl.Execute(os.Stdout, "no data needed") - if err != nil { - log.Fatalf("execution failed: %s", err) - } - -or to invoke a particular template explicitly by name, - - err := tmpl.ExecuteTemplate(os.Stdout, "T2", "no data needed") - if err != nil { - log.Fatalf("execution failed: %s", err) - } - -*/ -package template diff --git a/vendor/github.com/alecthomas/template/exec.go b/vendor/github.com/alecthomas/template/exec.go deleted file mode 100644 index c3078e5d0c0..00000000000 --- a/vendor/github.com/alecthomas/template/exec.go +++ /dev/null @@ -1,845 +0,0 @@ -// Copyright 2011 The Go Authors.
